Exoplanetology Current Affairs, GK & News
For the first time have Astronomers have discovered water vapour signatures in the atmosphere of a planet beyond our solar system that resides in the habitable zone (the region around a star which can support liquid water given sufficient atmospheric pressure). Discovery of Water Vapour in Habitable Zone The Astronomers from the Center for Space ..

For the first time, the astronomers at the University College London have discovered water vapour in the atmosphere of an Earth-size planet called K2-18b. They used data from NASA’s Hubble Space Telescope. The exoplanet “K2-18b” is 8-times the mass of Earth and known as a super-Earth. It orbits a red dwarf star 110 light-years away ..

The NASA scientists have characterized the first potentially habitable world outside our own solar system that may be suitable for life. The super-earth planet — named GJ 357 d — was spotted by NASA’s Transiting Exoplanet Survey Satellite (TESS) mission. It is estimated that planet is about six times the size of our planet and ..

The researchers at the University of Warwick in the UK have discovered a rogue exoplanet – NGTS-4b – with its own atmosphere in the Neptunian Desert. The Neptunian Desert is the region close to stars where no Neptune-sized planets are found. This area receives strong irradiation from the star, meaning the planets do not retain ..

The Transiting Exoplanet Survey Satellite (TESS) Mission of NASA has discovered its first Earth-size planet – HD 21749c. The newly-discovered planet is about 89% Earth’s diameter. The planet is likely very hot, with surface temperatures perhaps as high as 800 degrees F (427 degrees C). It orbits HD 21749, a K-type dwarf star located 53 ..

The ground based telescope picked up signals confirming planet revolving sun like star. The star belongs to the Milky Way galaxy. The star was identified using spectroscopic methods. It is in its white dwarf state. Eventually our sun is also likely to reach this stage in 5 billion years. As the star is running out ..
